Product details
Overview
R5F104FDGFP#50 from Renesas is a 44-pin LQFP, 32-bit RL78/G14 microcontroller with 32 KB flash, 4 KB data flash, 4 KB RAM, 10-bit ADC (16 channels), and real-time clock - designed for low-power industrial control applications operating from 1.6 V to 5.5 V.
For engineers reviewing the R5F104FDGFP#50 datasheet, R5F104FDGFP#50 pinout, R5F104FDGFP#50 application, or R5F104FDGFP#50 equivalent, key selection considerations include its -40°C to +105°C industrial temperature grade (G), LFQFP-44 package with 0.8 mm pitch, integrated UART/SPI/I²C interfaces, and ultra-low power consumption (66 μA/MHz active, 0.60 μA RTC+LVD mode).
Technical Context
The R5F104FDGFP#50 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (@32 MHz) to 30.5 µs (@32.768 kHz). It integrates a 12-bit interval timer, RTC with calendar/alarm, and watchdog timer driven by dedicated low-speed oscillator.
Peripheral integration includes up to 8× 16-bit timers (TAU, RJ, RD, RG), 4–10-channel I²C/simplified I²C, 3–4-channel UART/LIN, 3–8-channel CSI (SPI-compatible), and event-link controller (ELC) enabling hardware-triggered peripheral chaining without CPU intervention.
